The KM3NeT Collaboration is constructing new-generation neutrino detectors in the Mediterranean Sea. The main goals are the study of the highenergy neutrino flux and the determination of the neutrino mass ordering. The basic detection element, the Digital Optical Module (DOM), houses 31 3-inch PMTs inside a 17-inch glass sphere. The aim is to measure photons emitted by products of neutrino interactions in the sea-water with nanosecond precision. The multi-PMT concept has many advantages over a single-PMT design. We will discus these aspects and the enabling technologies. Additionally, the required mechanical and optical/electrical system on which DOMs are deployed as vertical strings, called Detection Units will be discussed.
